Abstract
The effect of carbonitriding as a finishing operation of hardening of the thread of drill pipes on the properties of the matrix metal, its temper brittleness in particular, is studied. The cold brittleness is evaluated with the help of tests for impact toughness. Steels for the production of drill pipe locks for operation at negative temperatures are recommended.
